Destroying Minecraft with a Kamehameha

A (Minecraft-like) game to destroy blocks with the Kamehameha and kill zombies.
This is a "conceptual game". It was developed only for learning and experimenting purposes. The project's source code is available on GitHub.
I scanned a real Goku's doll and put it into my game using free photogrammetry software. Also, I'm using Unity's HDRP, which allows me to create nice visual effects but requires a good GPU. (I'm using a GTX 1660 Ti.)
The game might be buggy and slow but bear with me. This is the first time that I try to create something playable with Unity. :)
MAKING OF:
HOW TO PLAY: Walk with WASD keys, jump with space bar and fire a kamehameha with left mouse click.
